Sampling device for titanium dioxide detection

Abstract

The invention discloses a sampling device for titanium dioxide detection. The sampling device comprises an extraction mechanism, the extraction mechanism is sleeved with a sampling mechanism, the bottom end of the sampling mechanism is fixedly communicated with a lower pressing disc, the extraction mechanism comprises an extraction pipe, the outer side of the extraction pipe is fixedly connected with the inner side of the sampling mechanism, and the top end of the extraction pipe is fixedly communicated with a collecting box; and the bottom of the collecting box is fixedly connected with the top of the sampling mechanism. The invention belongs to the technical field titanium dioxide detection. The sampling device for titanium dioxide detection can effectively solve the problems that in the prior art, in the packaging, transporting and storing processes, titanium dioxide is prevented from being extruded and agglomerated, titanium dioxide in a polyethylene bag needs to be sampled and detected regularly, only powder on the surface layer is observed and sampled and detected in the existing sampling process, the quality condition of deep powder cannot be determined, the sampling representativeness is also influenced, and the particle size difference and the distribution rule of titanium dioxide at different positions cannot be analyzed.

Description

technical field [0001] The invention relates to the technical field of titanium dioxide detection, in particular to a sampling device for titanium dioxide detection. Background technique [0002] Titanium dioxide is commonly known as titanium dioxide for pigments. It has a wide range of uses. As a white pigment with almost the best performance in the world, it occupies a large market share in coatings, plastics, inks, paper and other industries. In actual production and application, it is necessary to select different properties of titanium dioxide raw materials according to different industries and product uses, but the performance of titanium dioxide determines that it is not easy to transport, because the particles of titanium dioxide are heavy and abrasive. Design needs to be chosen carefully. [0003] Titanium dioxide has strong adsorption and corrosion, so it is difficult to transport stably, and it is easy to accumulate into agglomerates. Titanium dioxide is generall...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned shortcomings existing in the prior art, the present invention provides a sampling device for titanium dioxide detection, which can effectively solve the problem of preventing titanium dioxide from being extruded and agglomerated in the process of packaging, transportation and storage in the prior art. The titanium dioxide in the polyethylene bag is regularly sampled and tested. Existing sampling often only observes and samples the powder on the surface. The quality of the powder in the deep layer is not clear, and the representativeness of the sampling is also affected and cannot be analyzed. The particle size difference and distribution law of titanium dioxide in different positions
